Breaking bridges : Disila[2]molybdenocenophanedihydride was synthesized by dilithiation of 1,2‐bis(cyclopentadienyl)tetramethyldisilane and subsequent reaction with MoCl 5 in the presence of NaBH 4 . The photochemical conversion of the ansa complex leads to a highly unusual, twofold bridged [1],[1]molybdenocenophane (see scheme; C black, H white, Si pink, Mo violet).
